Hi,

Could some one please explain to me how the batch buffers in the drm
modules work.
Specifically, where do the commands for the batch buffer get setup and
where is it filled What information is typically contained in the batch
buffers?  How do commands get from the 3D driver via the batch buffer to
the graphics hardware.  For instance, if I want to display a pixel on
the screen, what are the steps that the 3D driver goes through to
actually put the pixel on the screen and what information does the 3D
driver need to communicate to the drm module.
appreciated

Cheers
Graeme
